IEC 60349-4:2012适用于构成电动轨道和道路车辆设备一部分的变流器供电永磁同步电动机或发电机（机器）。本部分的目的是通过试验确认机器的性能，并为评估其适用于特定任务以及与其他机器进行比较提供依据。应特别注意本标准中详细说明的机器及其相关转换器设计者之间的协作需求。

IEC 60349-4:2012 applies to converter-fed permanent magnet synchronous motors or generators (machines) forming part of the equipment of electrically propelled rail and road vehicles. The object of this part is to enable the performance of a machine to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty and for compa-rison with other machines. Particular attention is drawn to the need for collaboration between the designers of the machine and its associated converter as detailed in this standard.
